/** Test for Bug 694754 **/
/*
The following code tests if calling the DOM methods Document::lookupNamespaceURI
and Document::lookupPrefix directly (with quickstubs) and through XPCOM leads
to the same result.

This test makes use of the bug/feature that deleting a method from the 
prototype forces the engine to go through XPCOM.
